Journal ArticleDOI
Controlling mechanical properties of additively manufactured hastelloy X by altering solidification pattern during laser powder-bed fusion
Ali Keshavarzkermani,Reza Esmaeilizadeh,Usman Ali,Pablo D. Enrique,Yahya Mahmoodkhani,Norman Y. Zhou,Ali Bonakdar,Ehsan Toyserkani +7 more
TL;DR: In this article, the effect of scanning strategies and build orientations on solidification patterns in the printed LPBF Hastelloy X parts was studied. And the as-built microstructure (grain size, texture) and mechanical responses (yield strength, ultimate tensile strength (UTS), and elongation) were also presented.
Journal ArticleDOI
On the measurement of relative powder-bed compaction density in powder-bed additive manufacturing processes
Usman Ali,Yahya Mahmoodkhani,Shahriar Imani Shahabad,Reza Esmaeilizadeh,Farzad Liravi,Esmat Sheydaeian,Ke Yin Huang,Ehsan Marzbanrad,Mihaela Vlasea,Ehsan Toyserkani +9 more
TL;DR: In this paper, a nano-computing tomography (CT) system was used to obtain an estimation of the relative powder-bed compaction density along the recoater moving direction.
Journal ArticleDOI
An investigation into the effect of process parameters on melt pool geometry, cell spacing, and grain refinement during laser powder bed fusion
Ali Keshavarzkermani,Ehsan Marzbanrad,Reza Esmaeilizadeh,Yahya Mahmoodkhani,Usman Ali,Pablo D. Enrique,Norman Y. Zhou,Ali Bonakdar,Ehsan Toyserkani +8 more
TL;DR: In this paper, the effect of laser energy density on the melt pool geometry and microstructure of Hastelloy X single tracks produced by fixed LED values at different laser powers and scanning velocities was investigated.
Journal ArticleDOI
On the effect of spatter particles distribution on the quality of Hastelloy X parts made by laser powder-bed fusion additive manufacturing
Reza Esmaeilizadeh,Usman Ali,Ali Keshavarzkermani,Yahya Mahmoodkhani,Ehsan Marzbanrad,Ehsan Toyserkani +5 more
TL;DR: In this paper, the spatter formation and distribution on the powder-bed surface, due to the melt pool instability and flow field around the process zone, is considered as one of the drawbacks of this process.
Journal ArticleDOI
Identification and characterization of spatter particles and their effect on surface roughness, density and mechanical response of 17-4 PH stainless steel laser powder-bed fusion parts
Usman Ali,Reza Esmaeilizadeh,Farid Ahmed,D. Sarker,Waqas Muhammad,Ali Keshavarzkermani,Yahya Mahmoodkhani,Ehsan Marzbanrad,Ehsan Toyserkani +8 more
TL;DR: In this article, a comparative study is performed on the virgin and spatter powder particles where two types of spatter particles so-called: under-size (US) and oversize (OS) spatters are studied.
